A thicker front swaybar should help against this. Or a softer rear swaybar.

Hey all!
I am currently building this buggy for the first time and noticed my chassis is slightly bent downward on the rear end side. None of my other buggies have this so I was wondering if this was normal? I am nearly done building the buggy and everything fits perfectly though.

Thanks in advance.

running those tires will burn up pretty quick regardless. is your car unloading? (tires ballooning in front) if they are then run 10k in the center.
this makes the car accelerate more evenly and is good for initial hit as well.

What is the total weight of your car inc tires, battery, and body? Race ready.

And what battery and upgrades are you running?

Thanks.

Shock setup question for you guys:

Will 1.1 x 10 hole pistons have more pack than the 1.2 x 8, with the same oil?

Thanks.

Yes, more and smaller holes have more pack.

What springs are you all keeping on hand? Mainly run a dusty, low grip outdoor track that tends to get rough but smaller jumps. The other track we race at is a clay mixture outdoor track that is fairly smooth with larger jumps.

I recently put the Drake setup from the DNC race but couldn't get the ride height. Has anyone else had that problem?

1) shorten your front droop or lengthen your rear droop
2) thicken front shock oil
you have too much roll. weight transfers when you brake, accelerate and or during turns do all kinds of pressure on your suspension. these 2 suggestions should help.. I assume ride height is stock 24m front and 26m rear.

What should I change in my setup if my car feels very twitchy in the steering? If I move the wheel on the controller just a tiny bit it feels like the car turns a lot. And then I have to correct the steering the other way. Makes it hard to hold a race line.

Runing 10,7,5 I the diffs and around 600 front and 450-550 in the back shocks. Bars are around 2,4 front and 2,6-2,7 in the back. ( If I go thicker rollbar in the front I feel like I loose the ability to go around hairpins)

I also have the steering curve on my Sanwa set to -20.

Thanks inn advance.

Move the shocks in, move the steering links further back on the ackerman plate, thicker front diff, raise the camber links

Thank you for this. Found an human error on the settings of my Sanwa also 🥶.

Hello, I need new shock end balls. Does anyone know if any other brand will work other than Mugen? In a hurry and want to see if my LHS has something that will work.
